Description

Technical Field

[0001] The present application relates to the technical field of ignition guns, and in particular to an electronic ignition gun. Background Art

[0002] The electronic ignition gun is a pulse ignition tool that uses piezoelectric ceramics for ignition. It is used in environments where manual ignition is required, such as stove ignition in the kitchen.

[0003] In the related art, the electronic ignition gun includes a fuel tank body, an air pipe, a ignition needle, a pulse igniter, a mounting bracket, a needle cover, a button, an outer wind cover and other parts. During the installation process, it is necessary to assemble them multiple times in sequence to assemble the parts except the fuel tank body to the fuel tank body to obtain the assembly of the electronic ignition gun.

[0004] With regard to the above-mentioned related technologies, since the number of parts of the ignition assembly is large, the assembly process of the electronic ignition gun is slow, which is not conducive to improving production efficiency. Summary of the invention

[0005] In order to improve the assembly production efficiency of electronic ignition guns, the present application provides an electronic ignition gun.

[0006] The electronic ignition gun provided in this application adopts the following technical solution:

[0007] An electronic ignition gun, comprising:

[0008] The gas box body is used to provide gas and is provided with an embedding groove;

[0009] An ignition component assembly, which is detachably embedded in the embedding groove and is used to ignite the gas output from the gas box body;

[0010] The button assembly is arranged on the gas box body and is used to control the on and off of the gas output of the gas box body.

[0011] By adopting the above technical solution, during assembly, by integrating multiple parts into an ignition component assembly and a hand-pressing component, multiple installation steps can be reduced when the gas box body is assembled with the ignition component assembly and the hand-pressing component, which helps to further improve the assembly efficiency of the electronic ignition gun.

[0012] Optionally, the ignition component assembly includes an air pipe bracket, a fuel pipe and an igniter;

[0013] The embedding groove is used for the gas pipe bracket to be embedded and clamped, and the gas pipe bracket is provided with an insertion groove, and the insertion groove is used for one end of the fuel pipe to be inserted and output the fuel, and the other end of the fuel pipe is connected to the gas tank body;

[0014] The igniter is embedded in the embedding groove and arranged adjacent to the trachea support for emitting high-voltage electric sparks.

[0015] By adopting the above technical solution, the fuel pipe and the air pipe bracket are assembled and embedded into the embedding groove together with the igniter, so that the simple and fast assembly between the ignition component and the fuel tank body is achieved in an embedded installation manner.

[0016] Optionally, a limiting groove is provided on the inner wall of the embedding groove, a limiting ring is fixedly provided on the circumferential outer wall of the fuel pipe, and the limiting ring is embedded in the limiting groove for limiting.

[0017] By adopting the above technical solution, the setting of the limiting groove and the limiting ring increases the limiting firmness between the fuel pipe and the gas pipe, making it difficult for the fuel pipe to be relatively separated from the gas pipe bracket after assembly, which helps to maintain the fuel pipe to stably transport the gas.

[0018] Optionally, a positioning seat is fixedly provided on the edge side wall of the opening of the embedding groove, the positioning seat is arranged around the circumference of the embedding groove, the positioning seat is provided with a positioning slide groove, and the air pipe bracket is fixedly provided with a positioning block on the outer side wall close to the gas box body, and when the positioning block is slidably embedded to the bottom of the positioning slide groove, the fuel pipe and the gas box body are parallel to each other.

[0019] By adopting the above technical solution, the positioning groove and the positioning block are slidably plugged into each other. Under the limitation and guidance of the inner wall of the positioning groove, multiple trachea brackets can maintain their relative positions unchanged when installed with the corresponding gas box body, and further increase the limiting contact area of ​​the trachea bracket, which helps to increase the connection firmness between the trachea bracket and the positioning seat.

[0020] Optionally, an elastic clamping block is fixedly provided on the side wall of the positioning block away from the tracheal support, and the positioning seat is provided with a clamping hole, which is connected to the positioning slide groove. When the positioning block is slidably embedded in the bottom of the positioning slide groove, the elastic clamping block is clamped and embedded in the clamping hole.

[0021] By adopting the above technical solution, when the elastic clamping block slides along the inner wall of the positioning slide groove, the clamping hole allows the elastic clamping block to be embedded and clamped, so that the positioning block and the positioning seat are not easily separated from each other without human disassembly.

[0022] Optionally, a guide surface is provided on a side wall of the elastic clamping block away from the positioning block, and the guide surface has a tendency to guide the elastic clamping block to undergo elastic deformation.

[0023] By adopting the above technical solution, when the positioning block is embedded in the positioning groove, the guide surface guides the elastic clamping block so that the elastic clamping block undergoes elastic contraction, and the elastic clamping block recovers its elastic deformation when it moves to align with the clamping hole. The positioning block does not need to be manually pre-extruded and deformed when embedded in the positioning groove, thereby improving the convenience of assembling the tracheal stent.

[0024] Optionally, the side walls of the positioning block away from the gas box body are fixed with limit blocks, and the side walls of the positioning seat close to the positioning slide groove are provided with a receiving groove. When the limit block is embedded in the bottom of the receiving groove, the elastic clamping block is aligned and embedded in the clamping hole.

[0025] By adopting the above technical solution, the storage groove and the limit block cooperate with each other, and the limit groove provides a space for the limit block to be stored and embedded, so that the limit block is not easy to protrude from the surface of the positioning seat. While providing abutment limit for the positioning block, the elastic clamping block can slide just to the position aligned with the clamping hole, so as to further increase the installation firmness between the tracheal bracket and the positioning seat.

[0026] Optionally, a gas needle is fixedly provided on the gas box body, and a sealing ring is fixedly provided on the inner wall of the fuel pipe close to the gas box body. When the gas needle is inserted into the fuel pipe, the sealing ring fits tightly against the circumferential outer wall of the gas needle.

[0027] By adopting the above technical solution, when the gas needle and the fuel pipe are plugged in, the sealing ring can press the circumferential side wall of the gas needle, so that the sealing between the gas needle and the fuel pipe is further increased, and the probability of gas leakage from the connection between the gas needle and the fuel pipe is reduced.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] By integrating multiple parts into an ignition assembly and a hand assembly, multiple installation steps can be reduced when assembling the gas box body with the ignition assembly and the hand assembly, which helps to further improve the assembly efficiency of the electronic ignition gun;

[0030] The setting of the limiting groove and the limiting ring increases the limiting firmness between the fuel pipe and the gas pipe, so that the fuel pipe is not easy to be separated from the gas pipe bracket after assembly, which helps to keep the fuel pipe stable in transporting gas;

[0031] When the elastic clamping block is embedded in the positioning groove along with the positioning block, the guide surface guides the elastic clamping block so that the elastic clamping block undergoes elastic contraction. When the elastic clamping block moves to align with the clamping hole, the elastic deformation is restored. When the positioning block is embedded in the positioning groove, there is no need for artificial pre-extrusion deformation, thereby improving the convenience of assembling the tracheal stent.

[0040] The following is combined with Figure 1-7 The present application is further described in detail. In this embodiment, the direction indicated by the coordinate axis z in the figure is upward, and the direction opposite to the z axis is downward, and the coordinate axis is only used as a direction reference.

[0041] The present application embodiment discloses an electronic ignition gun. Figure 1 and Figure 2The electronic ignition gun includes a gas box body 1, an ignition component assembly 2 and a hand assembly 3. An embedding groove 11 is opened on the gas box body 1, and the embedding groove 11 is for the ignition component assembly 2 and the hand assembly 3 to be embedded, so as to complete the quick assembly of the electronic ignition gun. Compared with assembling multiple parts in sequence, it can reduce assembly time and help improve the assembly and processing efficiency of the electronic ignition gun.

[0042] Reference Figure 2 and Figure 3 The embedding groove 11 includes a first embedding groove 111 and a second embedding groove 112, which are interconnected. The ignition component assembly 2 includes a gas pipe bracket 21, a fuel pipe 22 and an igniter 23, and the igniter 23 is embedded in the second embedding groove 112. A gas needle 13 is fixedly arranged at the bottom of the first embedding groove 111. The gas needle 13 is connected with the butane in the gas box body 1 so that the butane forms a gas-liquid mixture for output. When the igniter 23 contacts the output butane through a high-voltage electric spark, the butane is ignited. The lower end of the fuel pipe 22 is sealed and plugged with the gas needle 13, and the upper end of the fuel pipe 22 is plugged and fixed with the gas pipe bracket 21. Under the limit of the gas pipe bracket 21, the fuel pipe 22 is not easy to shake.

[0043] Specifically, refer to Figure 4 The trachea bracket 21 includes a front bracket sleeve 211 and a rear bracket sleeve 212. The front bracket sleeve 211 and the rear bracket sleeve 212 are both provided with corresponding grooves. When the front bracket sleeve 211 and the rear bracket sleeve 212 are embraced with each other, the corresponding grooves form an insertion groove 213. At the same time, the front bracket sleeve 211 and the rear bracket sleeve 212 are arranged in a cylindrical tube shape. The insertion groove 213 connects the upper and lower ends of the trachea bracket 21. During installation, the fuel pipe 22 is inserted into the insertion groove 213 from bottom to top, and the upper end of the fuel pipe 22 protrudes, and the inner wall of the insertion groove 213 abuts against the axial side wall of the fuel pipe 22, so that the fuel pipe 22 is limited in the circumferential direction of the axis.

[0044] Reference Figure 4 and Figure 5 In order to prevent the front bracket cover 211 and the rear bracket cover 212 from separating easily after being embraced, the outer walls of the front bracket cover 211 and the rear bracket cover 212 are covered with a windshield shield 4. The windshield shield 4 is cylindrical, and the inner walls of the windshield shield 4 are in contact with the outer walls of the front bracket cover 211 and the rear bracket cover 212, so that the front bracket cover 211 and the rear bracket cover 212 are kept tightly embraced.

[0045] In addition, refer to Figure 4 and Figure 5A limiting groove 2131 is provided on the inner wall of the peripheral side near the lower side of the insertion groove 213. The limiting groove 2131 is provided in a ring shape and is coaxially arranged with the fuel pipe 22. A limiting ring 221 is fixedly provided on the outer wall of the peripheral side near the lower end of the fuel pipe 22. The limiting ring 221 and the fuel pipe 22 are coaxially arranged. During installation, the limiting ring 221 is embedded in the limiting groove 2131, so that the movement of the fuel pipe 22 in the vertical direction is limited, so as to further increase the installation firmness of the fuel pipe 22 in the insertion groove 213.

[0046] Reference Figure 2 and Figure 6 In order to further improve the sealing between the gas needle 13 and the fuel pipe 22, a sealing ring 222 is integrally provided on the inner wall of the circumferential side of the fuel pipe 22 near the lower end. The sealing ring 222 and the fuel pipe 22 are coaxially arranged. Since the inner diameter of the sealing ring 222 is smaller than the inner diameter of the fuel pipe 22, when the gas needle 13 is inserted into the lower end of the fuel pipe 22, the sealing ring 222 fits tightly against the circumferential outer wall of the gas needle 13.

[0047] Reference Figure 5 It should be noted that a positioning seat 12 is fixedly provided on the side wall along the upper side of the fuel tank body. The positioning seat 12 is arranged in a discontinuous arc-shaped sheet shape and is arranged around the peripheral edge of the first embedding groove 111. The two facing inner side walls of the positioning seat 12 are provided with positioning slide grooves 121. The two positioning slide grooves 121 extend into the first embedding groove 111 along the vertical direction. A positioning block 2121 is fixedly connected to the circumferential outer side wall of the rear bracket sleeve 212 near the lower end. There are two positioning blocks 2121, and the two positioning blocks 2121 are evenly arranged about the axis of the rear bracket sleeve 212. When the positioning blocks 2121 are embedded in and slide into the corresponding positioning slide grooves 121, the rear bracket sleeve 212 and the front bracket sleeve 211 remain parallel to the fuel tank body in the vertical direction.

[0048] Reference Figure 5 , the side walls of the two positioning blocks 2121 that are away from each other are fixed with elastic clamping blocks 2122. In this embodiment, the positioning blocks 2121 and the elastic clamping blocks 2122 are made of elastic plastic material, and the outer wall of the positioning seat 12 is provided with clamping holes 122. The number of the clamping holes 122 is the same as the number of the positioning slide grooves 121, and the clamping holes 122 are connected to the positioning slide grooves 121. When the positioning block 2121 is inserted into the positioning slide groove 121, the elastic clamping block 2122 is elastically deformed and fits against the inner wall of the positioning slide groove 121 until the elastic clamping block 2122 and the clamping hole 122 are aligned. The elastic clamping block 2122 restores its elastic deformation and is clamped and embedded in the clamping hole 122 to limit the downward sliding of the positioning block 2121.

[0049] In addition, the lower edge wall of the elastic clamping block 2122 away from the positioning block 2121 is provided with a guide surface 2123, and the guide surface 2123 is inclined from top to bottom toward one side of the adjacent elastic clamping block 2122, so that the guide surfaces 2123 on the two elastic clamping blocks 2122 are inclined from top to bottom towards each other. When the positioning block 2121 is inserted into the positioning slide groove 121, the guide surface 2123 has a tendency to drive the elastic clamping block 2122 to automatically elastically contract, so that the elastic clamping block 2122 can automatically elastically contract into the positioning slide groove 121 without manual adjustment, and it is not easy to limit the sliding of the positioning block 2121, making assembly more convenient.

[0050] Reference Figure 5 A limit block 214 is fixedly provided on the upper side of the two positioning blocks 2121, and the two limit blocks 214 are extended toward the side away from each other. A receiving groove 123 is opened on the side wall along the upper side edge of the positioning seat 12, and the receiving groove 123 is connected with the positioning slide groove 121 in the vertical direction. When the elastic clamping block 2122 slides in the vertical direction to align with the clamping hole 122, the limit block 214 is embedded in and received in the bottom of the receiving groove 123, further improving the limiting firmness of the positioning block 2121.

[0051] Reference Figure 7 It should be further explained that the hand assembly 3 includes a limiting shell 31 and a pressing shell 32. The two parallel edge side walls of the pressing shell 32 near the positioning seat 12 are fixedly connected with sliding protrusions 321. The two parallel inner walls of the positioning seat 12 near the positioning groove 121 are provided with guide grooves 124. The guide grooves 124 are provided for the corresponding sliding protrusions 321 to be embedded and slide in the vertical direction. The pressing shell 32 presses the igniter 23 during the downward sliding process to drive the igniter 23 to generate high-voltage electric sparks. The limiting shell 31 is tightly sleeved on the outer wall of the peripheral side of the positioning seat 12, and the upper side wall of the sliding protrusion 321 is abutted and limited so that the pressing shell 32 will not fall off during the sliding process. In addition, the upper side wall of the limiting shell 31 begins to have a clearance hole 311, and the clearance hole 311 provides clearance when the front bracket sleeve 211 and the rear bracket sleeve 212 are inserted.

[0052] The implementation principle of an electronic ignition gun in an embodiment of the present application is as follows: during installation, the igniter 23 is first embedded into the second embedding groove 112, and then the ignition component assembly 2 is embedded into the first embedding groove 111, so that the elastic clamping block 2122 is embedded and clamped into the clamping hole 122, and then the sliding protrusion 321 is aligned and embedded in the guide sliding groove 124, so that the pressing shell 32 is located directly above the igniter 23, and finally the limiting shell 31 is put on to complete the installation. The steps are few and the installation is convenient, which can further improve the assembly production efficiency of the electronic ignition gun.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
